The exact cause of bladder cancer is unknown. It occurs when abnormal cells grow and multiply quickly and uncontrollably, and invade other tissues. Smoking increases your risk of bladder cancer. Smoking causes half of all bladder cancers in men and women. The following factors also increase your risk of developing bladder cancer: exposure to cancer-causing chemicals at work.
Oil and natural gas are produced by the same geological process according fossil fuel suggestion: anaerobic decay of organic matter deep under the Earth's surface. As a consequence, oil and natural gas are often found together.In common usage, deposits rich in oil are known as oil fields, and deposits rich in natural gas are called natural gas fields.n general, organic sediments buried in depths of 1,000 m to 6,000 m (at temperatures of 60 Â° C to 150 Â°C) generate oil, while sediments buried deeper and at higher temperatures generate natural gas. The deeper the source, the drier the gas (that is, the smaller the proportion of condensates in the gas).
At higher temperatures, however, more natural gas is created, as opposed to oil. That is why natural gas is usually associated with oil in deposits that are 1 to 2 miles below the earthâs crust. Deeper deposits, very far underground, usually contain primarily natural gas, and in many cases, pure methane.atural gas is a vital component of the worldâs supply of energy. It is one of the cleanest, safest, and most useful of all energy sources. Despite its importance, however, there are many misconceptions about natural gas.
